If you haven't tried sleeping in a double sleeping bag before you might want to try it first.
I did the two bags zipped together thing for a few weeks last year, in our case it was because one bag was a lightweight summer bag and wasn't warm enough for the climate we were in. I really struggled with the restricted movement and rarely slept properly. The worst part is when your partners fast asleep then you can hardly even move trying to get more comfortable without waking them up.
If you normally sleep with matched body positions then it wouldn't be a problem, otherwise I suspect it would take some time to get used to it (I didn't, we got donated a second warm sleeping bag by some other travellers and went back to seperate bags).
Another concern with a double bag is when you get ill. Having to get up quickly during the night to deal with explosive shits or needing to vomit is even less pleasant if you're sharing a sleeping bag. (unfortunately I'm speaking from experience here - my advice is to blame it on her cooking!  )
